SCOTT OF UHTU SANITARY STRENGTH Application filed June 30,

The present invention relates to the construction of sanitary syringesor the like, such as are usually for the treatment and medication of thevagina and adjacent organs.

The object of the invention to improve upon structures heretoforedesigned for the same or similar purpose and to secure more thorough andeffective treatment of the or gans than with prior devices. it is anobject or" the invention to provide a device of this character which maybe easily inserted and expanded after insertion so as to eitectivelyreach all parts of the passage. it also an object to provide a device ofth character in which the solution, with. which the apparatus is to beused, can be readily and safely transported without danger of leakage orloss from evaporation.

These and other objects will be accomplished and secured by theinvention set forth and described herein, it being understood that whilethe disclosure and description are speciiic to enable those skilled inthis art to understand the same, it is by no means limited to exactconformity to such details and may be modified within the scope of thein vention as set forth in the claims.

In the drawings, in which the preferred form of the invention is shownFigure 1 is a side elevation of the completed device assembled, as, forexample, in carrying the same;

Figure 2 is a similar view, parts thereof being shown in section; and

Figure 3 is a sectional view with the outer casing removed as ready foruse.

The device, except as stated, is preferably made from a high-grade hardrubber compound, such as is usually employed in the manufacture ofmedical appliances. It consists of a ring or plug 1 of rubber or metalin which is frictionally held the nozzle 2 of a syringe, the outer endof which is formed with openings or discharge ports 3. The parts 1 and 2are held. together by the frictional contact of the inner end of thesyringe with the surface of the ring, but the parts may be readilyseparated for cleaning and for filling. The inner end of the nozzle is19%3. Serial No. fdii flil l.

provided with. a bead or groove to which is fitted a soit rubber bulb 5.

Elecured'in the rin 1 is an enpansible trame or core preferablyconsisting oi a plurality 01 out ardly extending wire spring members 6,which are preferably formed as loops and, when relieved oi any holdingttorce, expand out to a sutiicient extcn t to exp and the grind. Aboutthese spring members is secured a sponge rubber cap or swab 8 which.tits over the springs and is held in position near the ring by aclan'uging band or ring 9. This sponge rubber cap is of the ordinarymaterial oi' this nature and is highly absorbent, the small cells orpassages in the sponge rul her being'open sulliciently to permitthe pitssage of the inedicant through the sponge rubber and to permit absorptionby the sponge from the surrounding parts.

In order to permit the apparatus to be tilled and carried when. not inuse, a removable cap 10 is placed over the end cat the nozzle 2. For thesame purpose a tubular cover 12 is placed over the bulb 5 which its thering 1. A tubular sheath 15 is provided to cover the spring); 8 and toit over the cover 12, this sheath having a flaring mouth 16 to fit a'nst the body. This sheath is oi such dimen. one as to readily beinserted and will hold. the spring members compressed.

0 ii. removable cap 18 is fitted over the outer end of the sheath.

When the device is to be used, the syringe and its bulb and the cap 10are removed and the syringe is filled. The cap 10 is applied and thecover 19., sheath 15 and cap 18 are as sembied, as shown in Figure 1,the sheath compressing the spring; members and the sponge rubber cover.To use the device, he cap 18 is removed and the syringe inserted whilestill Within the sheath. The sheath is then removed by withdrawing overthe cover 12, which causes the spring meml ers to ere panel. The cover12 is then removed and by pressing upon the bulb, the contents oi? thebulb are forced into the sponge rubber. The sponge may then be rotatedwithin the passage, thoroughly cleansing and niedi satin; the tissues.The device may then be remove l and separated for cleaning and re-use.The

steps set forth may be varied slightly in their order, but theadvantages of the invention retained.

It Will be seen that there is provided an eX- tremely eflicientapparatus for the purposes set forth. The device is compact andeffective.

What is claimed is:

1. A device for the uses and purposes set forth, comprising a syringehaving a nozzle and a compressible bulb thereon, an expansibl e frameoverthe nozzle, an absorbent cap over the frame, and a sheath over thecap, said sheath retaining the frame and cap compressed but removablefrom the nozzle after insertion of the frame.

2. A device for the uses and purposes set forth, comprisinga syringehaving a nozzle and a compressible bulb, a cover over the bulb butremovable therefrom, an expansible frame surrounding the nozzle, anabsorbent cap over the frame, and a sheath over the cap, said sheathretaining the frame and cap in compressed condition but removable overthe cover after insertion of the frame.

3. A device of the class described, comprising a syringe, a nozzle onsaid syringe, a porous absorbent cap over the nozzle, means to expandthe cap, and a sheath over the cap to retain the same in compressedcondition during insertion but removable thereafter to permit expansionof the said means.

4. A device of the class described, comprising a syringe, a nozzle onsaid syringe, a porous eXpa-nsible and absorbent cap over the nozzle, anexpanding device Within the cap, and a sheath over the cap, said sheathbeing removable endwise of the syringe after insertion.

5. A device of the class described, comprising a syringe, a nozzle insaid syringe, a porous expansible and absorbent cap over the nozzle, anexpanding device within the cap, and a sheath over the cap, the internaldiameter' of which is smaller than the cap, said sheath being removableendWise of the syringe after insertion to thereby permit the expansionof the cap.

6; In a device for the purposes set forth, a syringe, a nozzle on saidsyringe, an absorbent sponge-like cap over the nozzle, and a sheath overthe cap, said sheath being removable BHClWlSG of the syringe afterinsertion.

7 In a device for the purposes set forth, a syringe, a nozzle on saidsyringe, an absorbent sponge-like .cap over the nozzle, a rigid sheathover the cap, said sheath being removable endWise of thesyringe afterinsertion, a compressible bulb on the syringe, and a cover over thebulb.

8. A device of the character set forth, comprising a syringe having anozzle and a com pressible bulb, a frame surrounding the nozzle,anabsorbent sponge on the frame,and a sheath surrounding the sponge, saidsheath being removable endwise over the bulb after insertion.

9. A syringe, comprising a ring, an expansible wire frame on the ring, anozzle seated in the ring and extending into the frame, a swab on theframe, and means to hold the frame in compressed position until afterinsertion.

10. A syringe, comprising a ring, an expansible Wire frame on the ring,a nozzle scat ed in the ring and extending into the frame, a porous,absorbent swab on the frame, and means to hold the frame in compressedposition until after insertion, said means consistof a tubular sheatnfitting over the ring but removable therefrom.
